WILHELM VON DHN', OF BERLIN-SCHNEBERG, GERMANY, ASSIGNOR TO HENNING G. TAUBE, OF MONTCLAIR, NEW JERSEY.

ATOMIZER.

To all whom 'it may concern:

Be it known that I, WILHELM voN DHN, a subject of the Empire of Germany, and a resident of Berlin-Schneberg, Helmstrasse 1, Pt., Germany, have invented certain new and useful improvements in Atomizers, of which the following is a specification;

This invention relates to atomizers or sprayers and more particularly to that class o these devices in which air or other fluid under pressure is utilized for projecting paint,varnishes or other liquids in a fine spray upon any iven surface.

Some of the o jects of this invention are the following: toutilize an atomizing agent or fluid under pressure so as to fully and completely atomize the outflowing liquid and to project said liquid outward with the best results; to regulate the outflow of the atomizmg agent and the inow thereof into the vesse containing the fluid; to utilize all of said agent at whatever pressure is desired without waste thereof; to provide ap aratus whereby the material can be atomize( either by suction alone or bythe combined action of suction and of direct pressure upon its surface; to provide means whereby liquids of different degrees of density may be atomized at will to provide a regulator permitting delicate regulation'of the amount `and pressure of the agent admitted upon the surface of the liquid and to provide apparatus for the above purposes of reliable and inexpensive construction easily assembled and cleaned.

This invention is illustrated in the accompanying` drawings wherein Figure 1 is a median vertical' section ofthe entire apparatus, Fig. 2 is a plan view thereof, Fig. 3 isv a partial cross section on the plane 3 3 of Fig. 2, Fig. 4 is a vertical section of the regulating valve, Fig. 5 is a horizontal section thereof, Figs. 6 to 17 are elevations of this valve in different positions, Fig. 18 is a vertical section of one form of discharge nozzle, Fi 19 is an end view of the same,` Fi s.

Specification of Letters Patent.

Application led July 26, 1906. Serial No. 327,813.

Patented .April 21, 1908.

In Fig. 1 the vessel for holding the liquid is shown at 1. This is closed by a metal covered tube and an annular elastic packing 3y held between a depending ring 4 within the vessel and an exterior covering ring outside. The ring 4 is provided with an integral cross bar 6.and the thumb screw 7 serves to fasten ring 4 in place, passing through the bar 6 into the cover 2.

The cover is held in place on the vessel by means of an up er frame 8 and a lower frame 9. The upper ame extends over the top of the cover 2 andv terminates on each side 1n a y hook 10. Each hook 10 engages with a link ing bar 12 which in turn is pivoted as at 13 to a bracket 14 on each side of the lower arm 9. By means of these links and clamps the cover can be easily adjusted and can then'be sub'ected .to tenslon by means of which the pac ing 3 is compressed and the cover is tightly sealed.

The up er frame 8 carries the princi al conduits fhr the com ressed air or ot er atomizing agent. Of t ese the main passage 15 passes through the handle 16 fastened to the arm 8 by means of the bars 17 and is then bent over into horizontal position across the top of the vessel 1, where it is joined to the main nozzle 18 by means of a sliding couplin sleeve 19 which is preferably provided wit, an upwardly extending bent strap 20 which serves as the handle.

At the top of the carrying handle 16 there is placed a valve case 21 Within which slides a plunger valve 22 havin an exterior thumb piece 23 and heldnorma y outward in closed position by the coiled spring 24. This valve can be conveniently worked by the thumb while the remaining fingers of one hand support the handle 16 thus regulating the action of the atomizing agent.

,- In the form of main nozzle shown in Fig. 1 the principal tube 18 is carried by a junction piece 25 which is carried by and is able to revolve upon the upright tube 26 carried by the frame 8. The inner tube 27 asses down into the vessel 1 and is provide with an extension 28 extendin to a point near the bottom of said vesse It' 1s through these tubes that the material to be atomized is discharged into the inner bent tube 29.

The exterior tip of the main nozzle is shown at 30. It comprises a suitably shaped tube surrounding the discharge tube 29 and..

slippiu over the end of the tube 18, being secure in placeby the thumb screw 31.

It will be seen that by the use of this construction the cou ling sleeve 19 can be slipped to the yrig t, permitting the main nozzle to be revolved upon the supporting tube 26 so as to make the interior of the nozzle and ofthe pipe' 15 both accessible for cleaning. v

In order to admit air from the tube -15 to the 'surface of the liquid within the vessel 1 a by-pass tube 32 leads from the side of the tube 15 into one side of the regulating valve 33 which communicates with the space in the top of the vessel 1 through the opening 34 (see Figs. 1, 3 and 4).

The regulating valve consists primarily of an outer sleeve 35 having an extension 36 passing through the cover 2 into the top of the vessel 1 and of an inner tube 37 fitting closely within the tube 35 and having an enlarged head 38 and provided with a horizontal lever 39 to facilitate the turning of one tube within the other. The tube 37 contains an inner core 40 having an extension 41 passing centrally through the tube 37 so as to leave a suitable space around it. Outer tube 35 is perforated on opposite sides as shown in Figs. 6 and 8. Through the smaller of these perforations 42, air is admitted through the pipe 32, while the larger perforations 43 communicate with the outer air. The inner tube-37 is also perforated onl opposite sides as shown in Figs. 7 and 9 and these latter perforations Which taper from one end to the other, as shown at 44 and 45, register respectively with the two op osite erforations 42 and 43 in the exterior s eeve.

he mode of use of this operating valve is clearly illustrated in Figs. 10 to 17. Figs. 10 and 1.1 show opposite sides of the valve with the inner tube turned so as to entirely close the inlet and partly close the outlet opening. In this position none of the compressed air or other ato'mizing agent is admitted to the vessel 1, but the whole stream of air is caused to iow out through the nozzle acting by suction in a well known manner to atomize the liquid which is drawn up through the -pipe 28. When it is desired to admit air to the surface of the liquid the amount of air ad mitted is determined by the position of the valve. If the maximum of air is to be admitted the valve is placed as shown at Figs. 4, 5, 12 and 13 where the wide, rounded end of each aperture 44 and 45 registers with the exterior apertures 42 and v43. This position is illustrated in Figs. 12 and 13 viewing the regulating Valve from opposite sides. If less air is to be admitted to the vessel the valve is turned as shown romopposite sides in Figs. 14 and 15 and a delicate adjustment is rendered possible by narrowing of the interior apertures toward one side as shown in Figs. 7 and 9. Fi s.,16 and 17' show the' position of the va ve from opposite sides which admits a minimum of air. By the use of a valve `of this character, ,the ressure Iregulating opening 43 is controlle simultaneously with the admission opening 42 and changes in one are made proportional to changes in the other. By carrying the air which is admitted from the Vessel 1 throu h the valve which regulates the opening to t ie exterior air I am able to use my apparatus with suction alone or if desired in combination with direct pressure within the vessel.

The core extension 41 is provided between the two openings so as to prevent the air from passing directly from one opening to the other and thus possibility of carrying liquid from the vessel 1 out through the opening 43 is prevented.

There it is desired to modify the forni and extent of the stream of atomized material I employ adjustable plugs such as are shown at 46 in Figs. 18 to 21. These are arranged to fit within the internal tube 29 and may bc given a form appropriate to the shape of stream to be produced. For instance the plug shown in Figs. 18 to 21 is iattened on one side so that a fiat ribben-like stream is produced.

`Where a Very fine stream is desired a choking tube 47 may be used which iits intoithe end of the tube 28 and a plug 48 of ap iopiiate size and shape can be fitted to sai( choking tube.

The form of nozzle shown in Fig. 25 can be fitted into the exterior nozzle 18 and coinprises an interior right angle junction 49 carrying a thumb screw 50 whereby the 'How of material can be controlled. The inner nozzle extends forward from the 'unction 49 as shown at 51 and may be fitted with any desired size of choking tube 52 which may be supplied with any ap ropriate form of lug 53 as above describe This last described form o nozzle is particularly adapted to the use of thin iuid suoli as japans and alcoholic veneers.
